Software-defined radio (SDR) is a radio communication system where components that conventionally have been implemented in analog hardware (e.g. mixers, filters, amplifiers, modulators/demodulators, detectors, etc.) are instead implemented by means of software on a computer or embedded system. [1]
GNU Radio is a free software development toolkit that provides signal processing blocks to implement software-defined radios and signal processing systems. It can be used with external radio frequency (RF) hardware to create software-defined radios, or without hardware in a simulation-like environment. It is widely used in hobbyist, academic ...
Eric Blossom is the founder of the GNU Radio project. [1] GNU Radio is a free software toolkit for building software-defined radio and signal processing systems. [2] His intention has been to build decentralized communication, moving away from infrastructure-based systems.
The Software Communications Architecture (SCA) is an open architecture framework that defines a standard way for radios to instantiate, configure, and manage waveform applications running on their platform. The SCA separates waveform software from the underlying hardware platform, facilitating waveform software portability and re-use to avoid ...
USRP – universal software radio peripheral is a mainboard with snap in modules providing software defined radio at different frequencies, has USB 2.0 link to a host computer; PowWow Power Optimized Hardware and Software FrameWork for Wireless Motes – hardware–software platform for wireless sensor networks
The OpenHPSDR (High Performance Software Defined Radio) project dates from 2005 when Phil Covington, Phil Harman, and Bill Tracey combined their separate projects to form the HPSDR group. [1] It is built around a modular concept which encourages experimentation with new techniques and devices (e.g. SDR , Envelope Elimination and Restoration ...
Software-defined radio (SDR) is a radio communication system where components, that have been traditionally implemented in hardware (e.g. mixers, filters, amplifiers, modulators/demodulators, detectors, etc.) are instead implemented by means of software on a personal computer or embedded system. [2]
The OpenBTS Um air interface uses a software-defined radio transceiver with no specialized GSM hardware. The original implementation used a Universal Software Radio Peripheral from Ettus Research, but has since been expanded to support several digital radios in implementations ranging from full-scale base stations to embedded femtocells.
